Operation with IR remote control
If enabled, function block 1 can be operated manually by remote control. In manual operation,
brightness and motion detection for function block 1 are switched off until automatic mode is
reset.
oSwitch on, e.g. light: Press the ¿ button.
oSwitch off, e.g. light: Press the Á button.
oSet automatic mode: Press the À button.
Manually changing settings with IR remote control
If enabled, individual settings for function block 1 can be changed during operation using a
remote control.
Sensitivity:
oIncrease sensitivity by one level: Press the ´ button.
oDecrease sensitivity by one level: Press the ² button.
oRecall set sensitivity again: Press ³ button.
iThe manual adjustment of sensitivity by the adjuster Sens. (7) is overwritten by the IR-
remote control and vice versa.

6 Information for electrically skilled persons
DANGER!
Mortal danger of electric shock.
Cover up live parts in the installation environment.
6.1 Fitting and electrical connection
Detection field and range
Figure 4: Detection field and mounting height
The size of the detection area depends on the mounting height(figure 4)and on the direction of
motion –(figure 5) ... (figure 8). As the distance to the detector increases, the detection density
and sensitivity decrease.

Selecting installation location
oSelect a vibration-free installation location. Vibrations can lead to unwanted switching.
oTo achieve optimum range, choose an installation location that is transversal to the
direction of motion.
oAvoid interference sources in the detection area. Interference sources, e.g. heaters,
ventilation, air conditioners, and cooling light bulbs can lead to unwanted detections.
Fitting the device
Prerequisite: Bus coupler (1) is mounted in an appliance box and connected.
oInstall the motion detector (3) with frame (2) onto the bus coupler (1) in the correct
orientation.
6.2 Commissioning
Load physical address and application program
oPress the AUTO / I button for approx. 5 seconds until the red LED in the lens lights up.

j0082597103 30.05.2017
Standard / Universal automatic switch 2.2 m

oAssign physical address.
The red LED goes out.
oWrite the physical address on the device label.
oLoad the application program into the device.
iIn case of active temperature measurement ("Universal" version) compare the temperature
measurement.
Testing the detection area
In the case of main units and extensions, check the detection areas of the devices individually.
Precondition: The device is installed and connected. The physical address is loaded.
oActivate the walking test:
Activate the parameter "Walking test after ETS programming" and download the
application software.
The device now operates brightness-independently. The PIR sensors are active according
to their programmed sensitivity.
oPace off the detection field, paying attention to reliable detection and interference sources.
Any motions detected are displayed by the blue LED.
oLimit the detection area as required. Adjust sensitivity with adjuster Sens. or IR remote
control, or change the programming.
oDeactivate the parameter "Walking test after ETS programming" and download the
application software.
Only for "Universal" version:
iIf enabled, the walking test function can be activated with the button Test of the IR remote
control.
